Perlite 10/20L



The primary role of expanded perlite in soilless growing mixes is aeration when added to peat moss, composts, coir and other water-holding aggregates. The porous surface of expanded perlite provides room alternately for both air and water in the mixes – each needed for vigorous root growth. Usage rates by volume vary from 5% to 40% for potting mixes, and as high as 75% to 100% in green roofs and hydroponics applications. Perlite use is increasing in agricultural and turf grass applications to break up compacted soils and retain water in dry climates.

Available in 10 and 20L Bags.
